Nothing Ordinary by E.M. Lindsey

Nothing Ordinary is a previously released serial novel in the Hit and Run series, now with 15,000 words of revised and additional content.
Ezra Mandel is many things:
A culinary genius.
A first-time teacher.
An anxious mess.
And helplessly attracted to the rudest, most grumpy man he has ever had the misfortune of meeting.
Ezra knows his first semester ever teaching at a private school is going to be a disaster. What he doesn’t expect is to get into a rivalry with the volleyball coach who can’t stand him. But the more he gets to know Gabriel Bassani, the more he starts to realize his pain is a lot deeper than the surface of his skin.
And Gabriel is a complicated man. He’s lived in the shadow of his MLB star brother for most of his life, his past marriage was a disaster, and he’s long-since stopped believing in love. But Ezra—persistent, beautiful, irritating Ezra—is the kind of man who refuses to give up, and Gabriel isn’t sure if he wants to beg him to stop, or beg him to keep going.
Whatever they have isn’t ordinary, but then again, ordinary isn’t something either of them has ever wanted.
